Shifters SL-SB00. These are actually last generation (1987-1990) friction only shifters. I like them as they use Suntours Power Control (ratcheted) friction shifting, but in a very small sleek package. The standard shifters for the first generation Superbe derailleurs where straight friction and worked well, but not as well as these! As you can see they are fill-engraved labeled "Suntour Superbe Pro".
